Built Data Integration and Reconciliation Framework for Settlement between a POS Credit Card Partner and Payment Network. Ensured real-time availability of high-quality data for firmwide PNL. Worked with stakeholders to come up with an optimal backfill strategy maintaining correct calculations in data snapshots at all times. Brought down run-time for a critical process from 55+ minutes to <1 minute enabling prompt data accessibility for analytics.Designed and implemented a common test… Show more Built Data Integration and Reconciliation Framework for Settlement between a POS Credit Card Partner and Payment Network.

Involved architectingmultiple data distribution channels for Customer Onboarding, Ledger Creation, Account Processing and Compliance leveraging tools like Confluent Kafka, Snowflake, firmwide Datalake. • Designed an EOD Processing and Alerting System ensuring Data Completeness, Quality and Availability before signaling Kick-start of critical data ingestions to downstream. Maintained different actions for different kinds of Checks - 1. Halt the entire processing for super critical breaks and generate alerts to stakeholders for timely resolution. 2. Generate informative alerts for data correction for non-critical breaks.• Designed Unified Ledger Data Models relevant across different LOBs like Personal and Commercial Loans, Cards and Deposits at Marcus by Goldman Sachs. • Led migration of on-prem Ledger domain data to strategic on-cloud warehouse built on AWS leveraging the unified models.• Built a system to facilitate Marketing Campaigns via a third-party vendor. An automated process for campaign Kickstart and Response Analysis led the firm to expand its customer base significantly.• Developed and managed a Springboot app to automate Role-based access provisioning to a Sybase IQ based warehouse.
